I have earned a bunch of TONcoin from past rounds, and I would like to cash it out. I've tried looking ways online, and most of them refer to gate.io or okx, though they block access to US citizens. (Im not sure if a VPN works, it seems like they do a government ID check) Is there any other way to sell them?

(PS codeTON round 8 later problems were very nice to solve!)

I enjoyed the recent division 3 contest! However, test case 7 was illegal. In the constraints of the problem, x and y had to have a positive absolute value. However, test case 7 had many queries where x was 0, violating the constraints.

The second query caused my solution and many others to fail :( Could someone take a look into this?
